3 Claims. (01. 128244) This invention relates to an expandible vaginal syringe.

A primary object of my present invention is to provide a novel, practical and improved form of I syringe that may readily be attached to a bag or any other suitable source of supply, to provide an adequate supply of fluid and avoid the nuisance of refilling as in the case of a bulb being used.

Another object is to provide a syringe having fingers which are readily assembled and easily detached for sanitary purposes.

Further advantages and objects of my improved syringe will be apparent as the description proceeds.

In the drawing Fig. 1 is an elevation showing the improved syringe in operative position.

Fig. 2 is in part an elevation and in part a vertical section of the syringe.

Fig. 3 is a side elevation of Fig. 2 with parts broken away.

Fig. 4 is a section along the line 4-4 of Fig. 2.

Referring to the drawing the syringe is provided with a frusto conical or hood shaped resilient support and actuator, preferably of'soft rubber. The said support and actuator comprises a conical side wall 1A with a head or partition 2 having a central aperture 3 adapted to receive a hollow nozzle 4. At the lower end of the wall 1A is indicated the inwardly and outwardly extending flange 1b.

The head or partition 2 is provided on diametrically opposite sides of the aperture 3 with slots 5 adapted to receive the shanks 6 of detachable expandible fingers 7. Said fingers 7 are concaved on their inner faces in planes at right angles to their longitudinal" axes as shown at 11. The nozzle 4 and fingers 7 are preferably made of hard rubber. The shanks 6 bear against the inner face of the conical wall 1A of the support or actuator 1.

The nozzle 4 has its upper end spaced below the upper ends of the fingers 7 extends below the head or partition 2 for the attachment of a hose 8 leading to a bag or other source of supply, and at its upper end the nozzle is provided with a plurality of perforations 9 for the ejection of irrigating fluid.

In actual use the hose 8 is connected to the source of supply of irrigating fluid and the curved, fingers 7 are inserted into the vaginal cavity, in advance of the nozzle.

A slight pressure by the operator upon the outer face of the conical wall 1A of the'support and actuator 1 will immediately swing the shanks 6 J toward each other and the fingers 7 will at once be swung to their spaced or open position. The portion of each shank 6 within its slot 5 functions as a fulcrum, and pressure is transmitted to the portion of the nozzle 4 positioned in the perforation 3 to lightly clamp said nozzle in place. When the operator bears upon the wall of the support and actuator 1, the lower portions of the shanks 6 approach each other and the material of the head 2 between the slots 5 and the perforation 3 is compressed. Upon the release of said support and actuator 1, the lower portions of shanks 6 will swing to their original spaced position resulting from the tension of the material of said head 2, to assume its normal position.

The expansion of the fingers 7 will cause the folds of the membrane of the vaginal vault to expand and at the same time the fluid is discharged through the perforations 9 of the nozzle and also through the ends 10 of the fingers '7. When pressure on the resilient support and actuator 1 is released the hard-rubber fingers 7 will automatically return to their folded position against the hard rubber nozzle 4 due to the resiliency of the soft rubber support and actuator 1.

Thus it may be seen that a thorough irrigation of the vaginal vault may be readily accomplished. I use only two of the fingers 7 so that practically the entire vaginal vault may be exposed to the fluid, and by a slight turn of the syringe the parts previously covered by the solid portion of the fingers may also be exposed to the fluid.

It will be noted that instead of the hose 8, a bulb could be substituted and the upper end of which could be detachably connected to the lower end of the nozzle 4,

The said bulb would be compressed when the walls 1A of the support and actuator 1 pressed by the user, the inward portion of the flange 1b bearing on the wall of said bulb.

Another feature of my improved syringe is'that passage of fluid through the hose 8 may be independent of the control of the fingers 7, if desired.

It is apparent from the foregoing that I have provided a simple practical and efficient form of syringe that maybe readily attached to any fountain bag to thoroughly clean the vaginal vault and at the same time obviating the necessity of a prone position on the part of the user.

While I have described my invention as embodied in concrete form and as operating in a specific manner in accordance with the patent statutes, it should be understood that I do not limit my invention thereto, since various modifications thereof will suggest themselves to those skilled in the art without departing from the spirit of my invention or the scope of the annexed claims.

What I claim is:

1. In a syringe of the character described the combination of a hood shaped support and actuator of flexible and resilient material, comprising a side wall and a resilient head, a nozzle extending through said head, fingers positioned around said nozzle and shanks at the lower portions of the fingers, said shanks extending through slots in said flexible and resilient head and into said hood shaped support and actuator,

said shanks approaching each other with thecollapse of said hood shaped support and actuator by the operator and said fingers simulta neously swinging to their open or spaced position, said shanks upon the release of said support and actuator swinging to their open or spaced position due to the tension of said head to assume its original position.

2. In a syringe of the character described the combination of a hood shaped support and actuator of flexible and resilient material, comprising a conical side wall and a resilient head, a nozzle extending through said head, fingers for the syringe positioned around said nozzle, and shanks integral with said fingers at the lower portion thereof, said shanks extending through slots in said head and bearing against the inner face of the conical wall of said support and actuator, said shanks approaching each other with pressure brought on the outer face of the wall of said support and actuator to collapse the same, and said fingers simultaneously swung to their open or spaced position, said head being compressed when said shanks approach each other and clamping said nozzle in place, said shanks upon the release of the wall of the support and actuator automatically swinging to their open or spaced position due to the spreading of said head to its original position and said fingers simultaneously swinging to their closed position.

3. In a syringe of the character described the combination of a frustro conical hood shaped resilient support and actuator, a resilient head integral with said support and actuator, said head having a central aperture and slots spaced from said aperture, fingers for the syringe, a shank integral with and extending from the lower portion of each finger, said shanks seated in the slots of said head and bearing against the inner face of the conical wall of said support and actuator, a hollow nozzle positioned in the aperture of the head of the support and actuator and extending below and above said head, the upper end of the nozzle spaced from and below the upper ends of said fingers, said nozzle having perforations and means detachably connected to the lower end of the nozzle for the supply of a fluid thereto.
